" AMALGAMATING y CELL;

'Application lerl October 22, 1921. Serial No. 509,665.

To all will matt mai/,concern Be it known that LCHAnLEs CoRLIss Mo- BRlDii, a citizen ofthe United: States, and

\ resident of Sangenin the county' of Fresno 5 and the'State of California, have invented a newand useful Improvement in'Amalg'gamat-y ing Cells, of which thefollowing is agspeciy` iication. f v

My vinvention relates to an electric amal gamator for separating metals from sand and ore pulp.

One object I'have accomplished is to pr0 duce a sluice having an amalgamated bottom which will be in contact with flowing mercury subjected rto a sodium chloride solution bath, and to an electric current, the sodium chloride' solution being constantly sealed from direct contact with'the contents ofthe v sluice. Y l j A further objectistozimprove the efficiency of the mercury by passing. a .current of electricity through a sodium chloride' solution 'tothe mercury, thus impregnating the mercury with `metallicsodium,'at the same time circulating'the mercury so as to bring it' into contact with ore pulp or sand containing precious metals, while said sand is being transported through the sluice by means which does not come in direct contact with the sodium chloride solution.

`I accomplish these and other objects hereinafter set forth by means of thedevice hereinafter described and illustrated on the accompanying drawing in which Figure 1 shows a topview of the device, showing a fractional View of the sluice. Figure 2 is a sectional view'of'the device along the line 2`2 in Figure l. Figure 3 is a sectional view f' of the device along the line 3-3 in Figure 1. My device consists of a sluice 'S havingk a bottom constructed `of an amalgamated plate C and two sides Band D1. Sides D and D1 project below the bottom plate C, said ex tensions being shown as l? and P1. A transand a grizzly is attached to the under surface of plate C sothat the grizzly will cover the opening. "On each 'side o f the sluice box and adjacent to the grizzly are boxes l box to an opening V1 inthe bottom ofthe mately to the broken line` N.

verse `seotion'fof bottom plate C is removed,

other box. Duct K passes `under the sluice and the plate C forms the top thereof. This duct is approximately the width of the grizzly j and passes directly` thereunder. A lineal sectional view of duct'K as shown in Figure 2 discloses the shape kof/the bottom to be two channelsl-l 'andHlllocated directlyunder the extensions P and P1, and in line therewith, said channels being connected with a member H2. The bottom of the duct is constructed water tight.

A tube T also connects compartments B and B1 extending from openings T1 and T2 in the bottoms of said compartments, which openings are a spaced distance from the` duct openings V and'V1. E is an electrical heater attached to tube T and adapted to heat themercury in tube T at a point adjacent lto theopening T2. The duct K and the bottom of compartments B and B1 are filled with mercury to the broken line M Which is approximately at the top of the grizzly and the compartments B and B1 are then filled with sea water, or with a solutionv containing sodium chloride approxi n Tt is noted that line N is arbitrarily formed, one feature of my invention consisting in having sea water or a solution containing sodium chloride within the compartments on the top of the mercury withoutregard to the exact v amountxtherein. T have placed anodes A and A1 within boxes B and B1 and have properly insulated them from the wal-ls of the boxes. These anodes should be located within the boxes so they will be immersed in the sea water or sodium chloride solution and so they are notincontact with the mercury therein. A cathode L is inserted in the bottom H2 preferably under the grizzly so that' it is immersedin` the mercury, and insulated from the box; The. anodes A and A1`and the cathode Ll are attached to a source of electrical energy, preferably to a direct ourrent.` i

In operating this device when the mercury and sea .water or sodiumchloride solution are within the duct and boxes as hereinbefore described and a direct current of electricity is introduced through anodes A and A1through the sodium chloride solui tion to themercury cathode, deposits of metallic sodium are gathered by the mercury extending under the bottom of the sluice, the duct having an opening in its top register- .ing with the opening in the amalgamated ing the bottom of container to the bottom of the amalgamated plate, a solution containing sodium chloride Within the container above the mercury, electric leads from a source of electrical energy to the mercury and to the solution containing sodium chloride, substantially as described.
